stuebinm 6afb255d97 nixos: remove all uses of lib.mdDoc
these changes were generated with nixq 0.0.2, by running

  nixq ">> lib.mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
  nixq ">> mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix
  nixq ">> Inherit >> mdDoc[remove]" --batchmode nixos/**.nix

two mentions of the mdDoc function remain in nixos/, both of which
are inside of comments.

Since lib.mdDoc is already defined as just id, this commit is a no-op as
far as Nix (and the built manual) is concerned.

# Note that generated /etc/zprofile and /etc/zshrc files do a lot of
# non-standard setup to make zsh usable with no configuration by default.
#
# Which means that unless you explicitly meticulously override everything
# generated, interactions between your ~/.zshrc and these files are likely
# to be rather surprising.
#
# Note however, that you can disable loading of the generated /etc/zprofile
# and /etc/zshrc (you can't disable loading of /etc/zshenv, but it is
# designed to not set anything surprising) by setting `no_global_rcs` option
# in ~/.zshenv:
#
# echo setopt no_global_rcs >> ~/.zshenv
#
# See "STARTUP/SHUTDOWN FILES" section of zsh(1) for more info.
